Hi everyone.
I have a couple of boiler/CH related queries.
I had an engineer come round to re-pressurise the expansion vessel fairly recently, as the CH pressure kept rising drastically; causing the PRV to activate. He fixed this issue but said that the boiler was not technically serviceable due to a lack of inspection point on the flue elbow.
The boiler is an Ideal Independent C24 and going through the manual I cannot seem to find anything on this kind of inspection point. I have read about probes being used from outside but access is an issue. I have attached a couple of photos of the top of the boiler - I am wondering if the small black screw cap has anything to do with this.
Also, because he drained the expansion vessel (and from the several times I had to top up the system), I am wondering if I should top up the inhibitor. He said it should be alright if enough was put in to begin with but unfortunately, having moved in a year ago, I don't know what had been done before. It seems that test kits available are for specific brands (and again I don't know which would have been used).
I am just concerned about the inside of the radiators corroding over time. Would my best bet be to bite the bullet; drain the system and add inhibitor?
Really appreciate any advice as central heating is definitely a bit out of my comfort zone for DIY.
